'AssoTrencher IV Mk9' sits at the top of mechanical trenchers range as it forms the latest version of the successful trencher series.
The AssoTrencher IV 9th upgrade is designed to cover the need for Post Lay Burial of flexible products in non-jettable seabed with increased production rates and assurance on the burial depth of the cable with the use of a powerful eductor suction system, or optionally a depressor system.
The design of the vehicle has incorporated all the advantages found in the previous arrangements of the Assotrencher IV Mk6 and in practice combines the ability to load heavy products (incl. bundled) with small to no slack in bottom-loading configuration, ensures trench cleaning with the use of its eductor suction system keeping this way the effectiveness of achieving the burial depth in hard/mixed soil conditions.
In addition and with the use of the depressor option, the vehicle ensures the trench geometry by using similar characteristics to the design of a plough, ensuring the burial depth in mixed soil conditions by using both trenching and jetting technologies.
